Oct 09, 2018 (Therese Pettigrew) - Sample H369255 assayed 0.534 ppm Au. Sample H369327 assayed 1.465 ppm Au (AFRI 20000004522). Lavigne et al. (1991) reported sheared, altered intermediate quartz-feldspar porphyry. There are two dominant shear directions: northeast (early) and east (late). Assays from northeast (early) set returned 100 to 900 ppb Au. Assays from east (late) set were as high as 9.00 g/t Au, 1448 ppm Cu and 4.5 ppm Ag.
